did some research but info seems to be kinda hard to come by... found a couple of websites that sell them... from what i know i'm looking for a wet nos kit and i think my car could take 100 shots... can someone confirm and clarify? any help would be appreciated... direct link to a 30 post nos thread if this was discussed already too would be fine i just couldn't find it on our cars specifically

There has been talk about this already but from what I have read it is very difficult. This is the thread I found on it. https://www.clublexus.com/forums/sho...d.php?t=263745.

bad idea. nos will destroy your car bit by bit.not recommended for a 40g+ car...

So will hard WOT starts without NOS. What is your point?

let me explain... i hope it makes sense to you guys or at least you can suggest something for me. i'm rarely a spirited driver... i mean i do go high speeds of around 80 on the freeway but most of the time i'm not even realizing i'm going that fast due to how sensitive our pedals are... this car doesn't seem to want to go slow

so anyway, i'm not spending 8500 for a SC that is only going to give me roughly 46 horses. From what i understand SC's are the most RELIABLE way to go... i'm not racing or going to be using the SC everyday and 8500 for something i rarely use doesn't make sense to me. Turbo from what i understand is unreliable BUT the best way to go if you want speed... and based on word of mouth NOS is the most unreliable of all. Though i been reading more about it doing some research and the websites are basically saying that it's unreliable and damages peoples cars because they don't have the right kit for their car... keep in mind though all of these options can hurt your engine no matter how you look at it. i will be using it sparingly roughly about once everytime we get together for the NELOC meets. maybe 3 or 4 times a year. I have someone special that i must stay ahead of... i won't drop names ... but do you guys think this is the best route for someone like me?

NOS kits can pretty much be installed on any car.All you need is an EFI NOS kit.And jets sized for the liter of your motor.Any good NOS co. can match up the specs for you.They do not make any IS kits because no one has been brave enough to try yet.(cars to new to market)You can make your own kit.A good bet would be a IS300 kit.You will just have to figure out where to tap the fuel.I was going to change out the bango fitting to a A/N bango with a tap for NOS line.I`ll be trying my own kit in the spring when it warms a bit ,too cold for NOS right now!LOL..

If you try, buy a Wideband O2 and make sure A/F ratios don`t get above 11 flat.Be safe batman.

It doesn't correspond with my experience at all. NOS works fine as long as it is set up right, and especially set up to avoid backfiring into a plastic manifold that will shatter under the right conditions. Nitrous backfires have killed more than one OEM Supra intercooler. I hate to think what might happen to our big (and likely expensive) intake manifold if there was a nitrous backfire.

Surely Lexus would cover an exploded intake manifold under warranty ...

I wonder about the physics of nitrous oxide in a stratified lean charge scenario. Its too bad Heywood doesn't cover this stuff more completely :-(... He does have a couple interesting pages on stratified-charge stuff, but nothing in depth, and, what a surprise, he doesn't cover nitrous injection to increase oxygen content and burn rates.

It seems to work well in diesel engines.This is were the idea for GDI motors started.They have done many studies on propane and nitrous in diesel motors.Nitrous does not combust on its own it only adds to the combustion process.Being said my question would be would the extra nitrogen in the mix actully slow the stratified lean burn?Nitrous added with fuel would burn off all the oxygen and extra fuel but the purpose is the change the bonding of oxygen and nitrogen during a stratified scenario.I quess it would depend on injection timing,which would be only when the valves open-would enter before the compression started.so what does this mean?Would it burn or just ping the cylinder?

Gernby

At the risk of being flamed ... doesn't air have a FAR greater nitrogen content than nitrous oxide?

I think the injection timing would have to change at WOT anyway.So this would totally cancel this prolbem out.No strafied lean burns at WOT.Just fuel and spark.This is why the port injectors are not used at WOT.Another question would be could the D/I with stand the high cylinder psi.Some diesels blow out their injectors.Your right Gernby.No flaming here.But only at atmos. psi.(nitro under psi changes the thinking alittle on this subject)btw props on the 13.0 1/4 mile....fastest known IS350...pimp`n
